Hello this is my scenario: DMZ has two servers the www hosted at internal IP 10.10.1.5 and mail hosted at 10.10.1.10. I have ISPconfig installed on www server. I would like to be able to be forwarder to the proper server when from Internet I go to www.domain.com and mail.domain.com Both servers are behind one firewall which has one public IP configured and I cannot add another IP. This is easy to do when internal destination ports are different (Port forwarding/ Destination NAT) however in my case both targeted ports are the same on both servers (80 and 443). I have been told that I could use reverse proxy on the apache server and this will take care of everything. I am not sure I know how to. Any help is much appreciated. I hope you will be able to understand my scenario and help me with a solution.
